4. Define a function divisibleDivisors(n, k) which takes n and k (n>=k)as its arguments and returns the number
of divisors of n which are divisible by k. Make use of the function to accept the values of n and k from the user and print
the number of divisors of n which are divisible by k.
Ans. def divisibleDivisors(n, k):
'''
Objective: Given n>=k, find the count of divisors of n which are divisible by k
Input Parameter: n,k - Integers
Return Value: count of divisors of n which are divisible by k
'''
assert n>=k
count = 0
for i in range(1, n + 1):
if (n % i == 0 and i % k == 0):
count += 1
return count

n = int(input('Enter a number n:'))
k = int(input('Enter k, n>=k:'))
count = divisibleDivisors(n, k)
print('number of divisors of', n, 'divisible by', k, '= ', count)
5. Define four functions—addition, subtraction, multiplication, and division that takes two numbers as input from the user
and returns the result of computation. Write a menu-driven program that takes two numbers as input from the user and
invokes appropriate function for addition, subtraction, multiplication, and division depending upon user's choice.
Ans. #Objective: To form a calculator
def menu():
"""
Objective: To display the menu
Inputs: NIL
Return value:
ch : Serial number of menu item selected by the user
"""
print(" MENU OPTIONS FOR CALCULATOR ")
print(" 1. Add ")
print(" 2. Multiply ")
print(" 3. Subtract ")
print(" 4. Divide ")
ch=int(input("Enter your choice : "))
return ch
def addition(num1, num2):
'''
Objective: To calculate sum
Inputs:
num1, num2 : numbers to be added
Return value: NIL
'''
sum = num1 + num2
print("The sum is ",sum)
def product(num1, num2):
